[Gastric pull-up reconstruction after pharyngoesphagectomy for advanced hypopharyngeal or cervical esophageal...

Objective: To analyze the clinical results of gastric pull-up reconstruction following total pharyngoesophagectomy. Methods: A total of 90 patients with hypopharyngeal or cervical esophageal cancinoma who underwent gatric pull-up reconstruction after pharyngoesophagectomy between June 2006 and June 2015 were reviewed retrospectively. Clinical data were analyzed. Rates of survival, recurrence and complicates were calculated with SPSS software. Results: Of 90 patients, 8 patients had hypopharyngeal cancinoma invading cervical esophagus, 51 patients had cervical esophageal carcinoma, and 31 patients had hypophageal and esophageal multiple parimary carcinomas. Forty patients were treated with surgery alone, 29 patients with planned surgery, and 21 patients with salvage surgery. After follow up of 6-104 months with a median of 22 months, 54 patients died and the total 3-year survival rate was 36.3%. Seventeen patients developed local recurrences and 10 patients cervical or mediastinal lymph node metastasis (LNM). The 3-year survival rates of patients with and without recurrence or LNM were respectively 5.9%, and 45.7% (χ²=11.564, P=0.001). Twenty-three patients developed distant metastasis. The 3-year survival rate of patients with and without distant metastasis were respectively 22.9% and 41.8% (χ²=4.534, P=0.033). Multivariate analysis showed local recurrence and distant metastasis as predictors for poor survival. The rates of perioperative mortality and anastomotic fistula were 3.3% (3/90) and 13.3%(12/90), respectively. Conclusions: Gastric pull-up reconstruction is a relatively safe and effective method for esophageal reconstruction after removal of hypopharyngeal or cervical esophageal carcinoma. Some patients could achieve good survival with low mortality and acceptable morbidity after multidisciplinary treatments.
